  • Implement sd_unlock_native_capacity() method which calls into
    hostt->unlock_native_capacity() if implemented. This will be invoked
    by block layer if partitions extend beyond the end of the device and
    can be used to implement, for example, on-demand ATA host protected
    area unlocking.

  • This patch creates a port_id member in struct fc_lport.
    This allows libfc to just deal with fc_lport instances
    instead of calling into the fc_host to get the port_id.

    This change helps in only using symbols necessary for
    operation from the libfc structures. libfc still needs
    to change the fc_host_port_id() if the port_id changes
    so the presentation layer (scsi_transport_fc) can provide
    the user with the correct value, but libfc shouldn't
    rely on the presentation layer for operational values.

    does not appear to provide anything useable in userland over the

  • If the scsi eh is running and then a FC LLD calls
    fc_remote_port_delete, the SCSI commands sent from the eh will fail.
    To prevent this, a FC LLD can call fc_block_scsi_eh from the eh
    callback, blocking the eh thread until the dev_loss_tmo fires or the
    remote port is available again.

    If (e.g. for a multipathing setup) the dev_loss_tmo is set to a very
    large value, thus preventing the scsi device removal , the scsi eh can
    block for a long time. For multipathing, the fast_io_fail_tmo is then
    set to a low value to detect path problems sooner.

    This patch introduces a new return code FAST_IO_FAIL. The function
    fc_block_scsi_eh now returns FAST_IO_FAIL when the fast_io_fail_tmo
    fires. This indicates that the LLD terminated all pending I/O requests
    and there are no more pending SCSI commands for the scsi eh to wait
    for. This return code can be passed back to the scsi eh to stop the
    escalation and finish the recovery process for this device.

  • When the kernel is configured for preemption, using smp_processor_id()
    when preemption is enabled causes a warning backtrace and is wrong
    since we could move off of that CPU as soon as we get the ID,
    and we would be referencing the wrong CPU, and possibly an invalid one
    if it could be hotswapped out.

    Remove the fc_lport_get_stats() function and explicitly use per_cpu_ptr()
    to get the statistics. Where preemption has been disabled by holding
    a _bh lock continue to use smp_processor_id(), but otherwise use
    get_cpu()/put_cpu().

    In fcoe_recv_frame() also changed the cases where we return in the
    middle to do a goto to the code which bumps ErrorFrames and does
    a put_cpu(). Two of these cases didn't bump ErrorFrames before, but
    doing so is harmless because they "can't happen", due to prior length
    checks.

    Also rearranged code in fcoe_recv_frame() to have only one call to
    fc_exch_recv(). It's just as efficient and saves a call to put_cpu().

    In fc_fcp.c, adjusted a FIXME comment for code which doesn't need fixing.

  • …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • commit 45465487897a1c6d508b14b904dc5777f7ec7e04 ("kfifo: move struct
    kfifo in place") caused a compile failure in ibmvscsitgt.c because it
    changed a pointer to kfifo in the libsrp.h structure to a direct
    inclusion without including .

    The fix is simple, just add the include, but how did this happen? This
    change, introduced at -rc2, hardly looks like a bug fix, and it clearly
    didn't go through linux-next, which would have picked up this compile
    failure (it only occurs on ppc because of the ibm virtual scsi target).

  • This is a new generic kernel FIFO implementation.

    The current kernel fifo API is not very widely used, because it has to
    many constrains. Only 17 files in the current 2.6.31-rc5 used it.
    FIFO's are like list's a very basic thing and a kfifo API which handles
    the most use case would save a lot of development time and memory
    resources.

    I think this are the reasons why kfifo is not in use:

    - The API is to simple, important functions are missing
    - A fifo can be only allocated dynamically
    - There is a requirement of a spinlock whether you need it or not
    - There is no support for data records inside a fifo

    So I decided to extend the kfifo in a more generic way without blowing up
    the API to much. The new API has the following benefits:

    - Generic usage: For kernel internal use and/or device driver.
    - Provide an API for the most use case.
    - Slim API: The whole API provides 25 functions.
    - Linux style habit.
    - DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros
    - Direct copy_to_user from the fifo and copy_from_user into the fifo.
    - The kfifo itself is an in place member of the using data structure, this save an
    indirection access and does not waste the kernel allocator.
    - Lockless access: if only one reader and one writer is active on the fifo,
    which is the common use case, no additional locking is necessary.
    - Remove spinlock - give the user the freedom of choice what kind of locking to use if
    one is required.
    - Ability to handle records. Three type of records are supported:
    - Variable length records between 0-255 bytes, with a record size
    field of 1 bytes.
    - Variable length records between 0-65535 bytes, with a record size
    field of 2 bytes.
    - Fixed size records, which no record size field.
    - Preserve memory resource.
    - Performance!
    - Easy to use!

    This patch:

    Since most users want to have the kfifo as part of another object,
    reorganize the code to allow including struct kfifo in another data
    structure. This requires changing the kfifo_alloc and kfifo_init
    prototypes so that we pass an existing kfifo pointer into them. This
    patch changes the implementation and all existing users.

  • So libosd has decided to sacrifice some code simplicity for the sake of
    a clean API. One of these things is the possibility for users to call
    osd_end_request, in any condition at any state. This opens up some
    problems with calling blk_put_request when out-side of the completion
    callback but calling __blk_put_request when detecting a from-completion
    state.

    The current hack was working just fine until exofs decided to operate on
    all devices in parallel and wait for the sum of the requests, before
    deallocating all osd-requests at once. There are two new possible cases
    1. All request in a group are deallocated as part of the last request's
    async-done, request_queue is locked.
    2. All request in a group where executed asynchronously, but
    de-allocation was delayed to after the async-done, in the context of
    another thread. Async execution but request_queue is not locked.

    The solution I chose was to separate the deallocation of the osd_request
    which has the information users need, from the deallocation of the
    internal(2) requests which impose the locking problem. The internal
    block-requests are freed unconditionally inside the async-done-callback,
    when we know the queue is always locked. If at osd_end_request time we
    still have a bock-request, then we know it did not come from within an
    async-done-callback and we can call the regular blk_put_request.

    The internal requests were used for carrying error information after
    execution. This information is now copied to osd_request members for
    later analysis by user code.

    The external API and behaviour was unchanged, except now it really
    supports what was previously advertised.

  • Administer some love to the osd_req_decode_sense function

    * Fix a bad bug with osd_req_decode_sense(). If there was no scsi

    * Add grossly missing in/out_resid to osd_sense_info and fill them in
    properly.

    * Define an osd_err_priority enum which divides the possible errors into

    places ...

  • The true logic of this patch will be clear in the next patch where we
    use the class_find_device() API. When doing so the use of an internal
    kref leaves us a narrow window where a find is started while the actual
    object can go away. Using the device's kobj reference solves this
    problem because now the same kref is used for both operations. (Remove
    and find)

    Core changes
    * Embed a struct device in uld_ structure and use device_register
    instead of devie_create. Set __remove to be the device release
    function.
    * __uld_get/put is just get_/put_device. Now every thing is accounted
    for on the device object. Internal kref is removed.
    * At __remove() we can safely de-allocate the uld_ structure. (The
    function has moved to avoid forward declaration)

    Some cleanups
    * Use class register/unregister is cleaner for this driver now.
    * cdev ref-counting games are no longer necessary

    I have incremented the device version string in case of new bugs.

  • Patch and mail from both MikeC and HannesR:

    Before we're trying to send a PDU we have to check whether a TMF
    is active. If so and if the PDU will be affected by the TMF
    we should allow only Data-out PDUs to be sent.

    If fast_abort is set, no Data-out PDUs will be sent while
    a LUN reset is being processed for a affected LUN.

    fast_abort is now ingored during a ABORT TASK tmf. We will not
    send any Data-outs for a task if the task is being aborted.

  • Some of our virtual SCSI hosts don't have a proper bus parent at the
    top, which can be a problem for doing DMA on them

    This patch makes the host device cache a pointer to the physical bus
    device and provides an extra API for setting it (the normal API picks
    it up from the parent). This patch also modifies the qla2xxx and lpfc
    vport logic to use the new DMA host setting API.

  • Customers and certification tests have pointed out that we don't
    show up on the switch management software as an initiator.

    On some MDS switches 'show fcns database' command shows libfc
    initiators as 'fcp' not 'fcp:init' like other initiators.

    On others switches, I think the switch gets the features by doing a PRLI,
    but it may be only certain models or under certain configurations.

    Fix this by registering our FC4 features with the RFF_ID CT request
    after local port login and after the RFT_ID.

  • There was a locking problem where the fip->lock was held during
    the call to update_mac(). The rtnl_lock() must be taken before
    the fip->lock, not the other way around. This fixes that.

    Now that fcoe_ctlr_recv_flog() is called only from the response handler
    to a FLOGI request, some checking can be eliminated. Instead of calling
    update_mac(), just fill in the granted_mac address for the passed-in
    frame (skb).

    Eliminate the passed-in source MAC address since it is also in the skb.

    Also, in fcoe, call fcoe_set_src_mac() directly instead of going thru
    the fip function pointer. This will generate less code.
    Then, since fip isn't needed for LOGO response, use lport as the arg.

  • This is to notify the LLD when an FC_ID is assigned to the local port.

    The fnic driver needs to push the assigned FC_ID to firmware.
    It currently does this by intercepting the FLOGI responses, and
    in order to make that code more common with FIP and NPIV, it
    makes more sense to wait until the local port has completely
    handled the FLOGI or FDISC response. Also, when we fix
    point-to-point FC_ID assignment, we'll need this callback as well.

    Add a call to the libfc template, which is called whenever
    the local port FC_ID is being assigned. It defaults to
    fc_lport_set_fid(), supplied by libfc.

    As additional benefit of this function, the LLD may determine
    the MAC address that caused the change by looking at the received frame.

    We also print the assigned port ID as long as it isn't 0.
    Setting port ID to 0 happens often in reset while retrying FLOGI,
    and would be uninteresting. This replaces the previous message
    which didn't identify the host adapter instance.

    patch v2 note: changed one word in a comment. "intercepted" -> "provided".

  • The strncpy for RSPN_ID and RSNN_NN requests was padding
    past the allocated frame size.

    Get the string length before filling in the ct header.
